How to choose
Choose the Litter-Robot 4 if you have up to 4 cats; choose the PetSafe ScoopFree SmartSpin only if you have exactly 1 cat, as it is limited to single-cat households.
The CatGenie requires a direct connection to a water line and drain, making it suitable only if you can handle plumbing installation; other models are plug-and-play.
Factor in ~$25/month per cat for CatGenie cleaning cartridges; Litter-Robot models require periodic replacement filters and liners, while PETKIT uses standard clumping clay.
Measure your space carefully for the Litter-Robot 4, which is approx. 30" tall and 25" wide; the PetSafe ScoopFree offers a low-profile alternative for tighter areas.
